IMPROVED ARTIFICIAL-FUEL.

Specification forming part of Letters Patent No. 48,4 39, dated June 27, 1865.

,;To all whom it may concemr Be it known that I, HENRY REDLioLu'of Chicago, Cook county, State of Illinois, have invented a new and useful Improvement in Aggregating Goal-Dust, Sawdust, &c.; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to fully understand and use the same.

This invention relates to an improved method of aggregating coal-dustor waste coal, and also sawdust and other similar combustihles, by mixing them with a certain percentage of 'cowmanure, with or without blood, and compress ing the mixture so as to drive out all moisture and to produce cakes of the requisite form and consistency.

Tl1fl l)l0[)0ltl0ll in which I mix the ingredients of my composition together is about as follows: hard-coal dust, four parts,by weight; fresh cow-dung, three parts, which leaves, after dripping and pressing, only six parts, because all the moisture contained in the cow'- dung is expelled. Or, instead of the above, I have used with advantage the following proportion hard-coal dust,t'our parts; fresh cow dung, three parts; blood, one part, which, when mixed, pressed, and dried, leaves only six parts, because all watery matter of the cow-manure and blood dries out.

If I have soft-coal dust instead of hard-coal dust, the proportion is slightly changed; and I have used with good result the following proportion: soft-coal dust, four parts; cow-dung, two parts, which I mix, as above, in a mortar .or any other suitable reservoir, and press and dust, which is considered worthless, and can be got for a mere trifle. Oow manure also can be procured everywhere at a small. expense,

and, it being combustible and not a good cona doctor of heat, it promotes the burning-of the coal. Furtlu-rmore, by this branch of industryalargo portion of coal will beused up,and the health of the neighborhood willbe improved.

I claim as new and desire to secure by Letters Patent- The within-described combination of the ingredients above specified, and. mixed together substantially in the manner and about in the proportion set forth.
